ELECTRIC RETOUCHER.

Application led May n 20.

To all whom t may concern.

Beit known that I, VICENTE A. RAGAZA, a citizen of 4the United States,residing at Cebu, Cebu, yPhilippine Islands, haveinvented certain newand useful Improvements-in Electric Retouchers; and I do hereby declarethe following to be a full, clear, and exact' description ofthekinvention, such as will enable others skilledk in the artto which itappertains to make and use thesame.

This invention has relation to certain new and vuseful improvements inretouchers and has for its primaryobject, the provision of an electricretoucher which will be of simple construction and operation and highlyetlicientin use. .n

The invention has for another object, the provision of any electricretoucher' which is specially adapted for use kby photographers forretouchingphotographic plates and lms and which will be operated in sucha manner that the most delicatel operations of re-V touchingmay beperformed quickly and efiiciently without danger of'injuryto the Theinvention has y'for a `further object, the

rovision of an electric retoucher which will ide ofisimpleand compactform and constructed in suchia manner that the operator orretoucher mayconveniently hold the device and operate the switch thereof with` thethumb or a linger tostart or stop opera-I tion .of the retoucher, asdesired. I

The aboveand other objects, in view, as will appear yas l thedescription .f proceeds, the invention consists in the novel combinationand arrangement ofv coperating elements employed to produce the?complete' device, as will be hereinafter more specifically set forth,claimed and shown in theaccompanying drawings formingk a part of thisapplication-and-in which Figure 1 is an elevationof the complete device.

in which similar reference characters designate corresponding partsthroughout?y the several v1ews,1 indicates the cylindrical casmg' whichtapers toward itsV forward'-y end and has an offset portion 2 on oneside intermedlate its forward and-rearfends. The reary end is closed byalscre'w cap 3 mounted thereon and having'an' insulated'fface'fipositioned therein and withinv which is@ embedded oneend of the'leaf'spring/5, the opposlte end of which is secured uponV the rear endportion of the armature 6, bysuitable securing' members 7.Tl1e'securin'g1members 7 also serve'to securev tothe armature 6y and thespring,v 5, the offset endv of the 8, which latter has the` platinum.tip or contactpointQ" on its outer or free'end portion normallycontacting-,with the point of the contact screwy 10 which is threadedthrough the upper side of the casing 1, as clearly shown in thedrawings. The armature 6 is preferably `of velozugated form and isnormally spac'edfrom` the electromagnetll',which latter is `mounted upontheinner face of the insulating 'supporting plate 12 whichl issecuredtthe'casmg 1 and closes the lovcf'erfopen side-ofthe offsetportion of "said casingfl, suitablesel curin'gf members A13 being"'employed `to` 'se cure the supporting-'plate 12 in `positio'nloppositethe"-adjustable contactfscrew "10.: A

against the action of the spring 5. The spring 5 will immediately act toreturn the armature 6 and bring it to normal position,

thereby closing the circuit through the electromagnet l1 and denergizingthe same. As soon as the point 9 of the screw 8 returns to engagementwith the spring 10, however, the circuit will again be completed throughthe electromagnet l1 to energize the latter and cause a second movementof the armature 6 toward the magnet 11. This operation will be continuedas long as the switch 14 is Closed over the switch contact points 19 and20, causing a continual oscillation or vibration of the armature 6. Thecontact screw l0 may be readily adjusted in the side ofthe casing l toregulate the length of the movement or vibration of the armature 6 theadvantages of which will presently appear.

The casing l is preferably formed of insulating material and has itstapered forward end open, as shown at 22 and through which projects theforward longitudinally slotted end 23 of the pencil or lead carryingtube 24, the inner end of which connects with the forward end of thearmature 6. The lead member 25 of the retouching pencil may be readilyengaged within the tube 24 with its pointed ends projecting therefromand in order to securely clamp the lead 25 in position, l have provideda conical collar or tubular clamping member 26 having both ends open andits forward end rounded, as shown at 27. The inner end portion of theclamping member 26 is interiorly threaded, as shown at 28 for adjustableengagement on the exteriorly threaded forward end portion 29 of the tube24, inwardly of the forward endof the casing l. It will therefore beseen that when the lead 25y is engaged in the tube 24 and the clampingmembers 26 engaged over the tapered end of the lead 25 and threaded uponthe tube 24, the forward end of said tube 24 with its longitudinal slotstherein will clamp around the lead 25, owing to the tapered shape of theclamping member 26, to securely hold the lead 25 in adjusted position,thereby presenting outwardly of the end of the clamping member 26 theproper portion of the tapered or pointed end of the lead 25. It willalso be seen that the exterior diameter of the portion of the clampingmember 26 extending through the open end 22 of the casing l is less thanthe diameter of the open end 22, thereby permitting free oscillation orvibration of the tube 24 and the lead 25 therein with the armature 6during use of the device.

From the foregoing description, taken in connection with theaccompanying drawings, it will be evident that it will simply benecessary for the operator to grasp the handle, move the device toposition opposite the portion of the photographic plate or film to beretouched and hold the device while pressing inwardly the switch 14 tocomplete the circuit through the electromagnet 1l, thereby causingproper oscillation or vibration of the lead pencil 25 while the pointsthereof are in contact with the film. The most delicate operation in thework of retouching may be performed with this device even by those whoare not sufficiently skilled to perform this work by hand, as suchoperations by hand call for considerable knowledge in this art andability to move the hand freely and accurately at the wrist, and alsomove the arm at the elbow and shoulder. The lines can be applied to thefilm without injury thereto and in such a manner as to remedy defects inthe film and also prevent printing of wrinkles and other objectionablelines and marks on the photograph which may either have beenphotographed from the subject or caused to appear on the film as theresult of injury thereto or a slight defect in the film. This form ofelectric retoucher mty be readily employed in all operations ofretouching and will sufficiently perform the work in a much shorter timethan can be done by hand.

lhile the preferred embodiment of the invention has been shown anddescribed, it will be understood that I do not wish to be limitedthereto, as many minor changes in the details of construction andarrangement of parts may be resorted to within the scope of what isclaimed without departing from the spirit of the invention.
